Description

Searchlight for Vehicle

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to searchlights for vehicles, and more particularly to openable searchlights provided in the center of a rectangular patrol light for use in police vehicles and rescue vehicles.

Rectangle warning lamps are widely used in patrol cars and in various ways in emergency vehicles and ambulances for rescue and lifesaving. Rectangle warning lights installed on the roof of the patrol car have a transparent case of red and blue, and a speaker cover with a built-in speaker is usually located at the center. In addition to these general warning lights, searchlights were installed at the center of the rectangular warning lights to prevent disasters, life-saving or crime at night, and search for criminals. This content is published in Utility Model Publication No. 2000-012869.

6, a plurality of reflecting lights 52 and flash lamps 53 are installed in the transparent cases 51a and 51b, respectively, and the upper and left sides of the speaker network 54 are provided by a motor. The searchlight head 55 which can rotate is provided, and the beamlight 56 which can rotate up and down by the motor was built in this searchlight head 55. As shown in FIG.

However, the conventional design as described above has excellent practicality because the search head of the cylindrical and flat streamlined body protrudes above the speaker network (speaker cover) in which the speaker is built, but the design was not refined, which hindered the export. . In addition, even if the searchlight is not used, since the searchlight head always protrudes to the outside, foreign matters such as dust often get stuck in the front glass (light cover) of the searchlight head, and thus the inconvenience of having to clean it at all times was also followed.

The object of the present invention is to keep the exterior of the speaker cover of a rectangular warning lamp (flat) outside and to keep the searchlight head protruding to the outside only when used, so that the unsophisticated design is improved and the light cover is dusty. It is to provide a searchlight for a vehicle in which foreign substances such as back are not frequently caught.

The present invention, in order to achieve the above object, a searchlight head which can be rotated left and right about the lower rotating shaft and the beam light which can be rotated vertically by a vertical rotation motor, and a rotating shaft of the searchlight head are installed and The left and right rotation motor for rotating the rotation shaft to the left and right is fixed and joints vertically movable from one side of the case, and searchlight head opening and closing means for turning the free end of the bracket up and down by screwing in the vertical direction according to the driving force of the opening and closing motor And a position detecting sensor for detecting the front position of the searchlight head, and outputting to the open / close motor if the position detecting sensor is connected at the time of selecting the open / closed mode of the external switch. According to the up / down rotation mode and the closing mode, the up / down motor and the left / right rotation motor And it was adapted to the opening and closing motor includes a controller which selectively outputs, respectively.

According to the present invention having the above configuration, when the external switch is selected as the open mode, the searchlight head is opened while the free end of the bracket is turned upward by the operation of the searchlight head opening and closing means according to the driving of the open / close motor. At this time, the beam light can be turned off. When the external switch is selected as the vertical mode, the beam light is rotated up and down according to the driving force of the vertical motor. If the external switch is selected as the left and right mode, the rotating shaft of the searchlight head is rotated according to the driving force of the left and right rotation motors, and the searchlight head is rotated left and right. When the external switch is set to the closed mode, the search motor head is driven first to the left and right rotational motors at any position, and accordingly, if the position sensor is activated when the search head head is facing forward, the open / close motor is driven to lower the free end of the bracket. The searchlight head is closed and stored while turning.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 is a cross-sectional view of the searchlight operation structure, the searchlight head is open, Figure 2 is a cross-sectional view of the searchlight head is closed, Figure 3 is a cross-sectional view of the interior beam light is rotated upward when the searchlight head is opened. 4 is a cross-sectional view of the beam beam of the interior rotated downward while the searchlight head is rotated 180 °. 5 is a perspective view of a rectangular warning light with the present invention installed and showing a state in which a searchlight head is opened. However, the signal system by the controller is shown in blocks only in FIG.

The searchlight head 1 is covered with a transparent circular lens 3 on the front of the case 2, and the beam light 4 is installed to rotate vertically about the hinge pins 5 on both sides. More precisely, the portions indicated by dotted lines in FIGS. 1 and 2 are fixed to the inside of the light cover 6 having the hinge pins 5 on both sides as the beam light 4. The hinge pin 5 is rotatably fitted to both side walls of the case 2. At the rear of the light cover 6, a vertical rotation motor 7 is provided, and the vertical rotation motor 7 is fixed to the case 2. Between the upper rear side of the light cover 6 and the shaft of the vertical rotation motor 7 is provided so that the two-section link 8 can crank. Thus, when the vertical rotation motor 7 rotates forward or reverse, the light cover 6 rotates upward or downward about the hinge pin 5. The up and down rotation motor 7 is driven by the controller 9, and the controller 9 is formed by an upward or downward mode signal sent from a switch SW mounted in a driver's seat or attached to a wireless remote controller.

The rotary shaft 10 is formed below the searchlight head 1. The center of the rotation shaft 10 is hollow so that the wires going to the vertical motor 7 and the beam light (4) can pass through. The gear 11 is fitted to the upper portion of the rotary shaft 10 and is fixed to the case 2 and the rotary shaft 10. The lower part of the rotating shaft 10 is built in the bearing 12, and this bearing 12 is being fixed to the bracket 13. As shown in FIG. Therefore, the searchlight head 1 is in a state capable of rotating from side to side on the bracket 13.

The bracket 13 is provided at one end of the hinge 15 formed on the inner wall upper side of the lower case 14, and the other end (free end) is directed to the lower part of the searchlight head 1. The bracket 13 is provided with the rotary shaft 10 of the searchlight head 1 as well as the left and right rotary motors 17 for driving the gear 16 engaged with the gear 11 installed on the rotary shaft 10. That is, the gear 16 is installed on the shaft of the left and right rotational motor 17 and the left and right rotational motor 17 itself is fixed to the bracket 13. Moreover, the slot 18 is formed in one side surface of the bracket 13. The slot 18 is formed so that the pin 20 protruding from the side of the female screw gear 19 which forms an element of the searchlight head opening and closing means can be guided from side to side. That is, when the female screw gear 19 moves up and down while turning the free end of the bracket 13 up and down, the center point of the female screw gear 19 is also compensated for to change in the transverse direction, and also serves as a support point of the bracket 13. This is the slot 18 of the bracket 13.

The search head head opening and closing means comprises a female screw gear 19, a male screw gear 21 which is screwed with the female screw gear 19, and a worm 23 driven by the opening and closing motor 22. As described above, the female screw gear 19 can move laterally along the slot 18 of the bracket 13 and is also fitted to the male screw gear 21. Thus, when the male screw gear 21 rotates left and right, the female screw gear 19 is screwed up and down (vertical direction). The male screw gear 21 has its lower end arranged in the bearing 24, and the outer ring of the bearing 24 is fixed to the lower case 14 side. The male screw gear 21 rotates left and right by the worm 23. The worm 23 is operated by the forward and reverse rotation of the opening and closing motor 22. Therefore, when the worm 23 rotates the male screw gear 21 in the forward or reverse direction by the opening / closing motor 22, the free end of the bracket 13 is turned upward or downward while the female screw gear 19 is raised or lowered. Accordingly, the searchlight head 1 protrudes in the lower case 14 and is opened or received and closed.

The position sensor was composed of a limit switch 25 and a stopper 26. The limit switch 25 is connected by the contact of the stopper 26, and is provided in the upper end side surface of the bracket 13. As shown in FIG. The stopper 26 is provided in the gear 11 under the searchlight head 1. The stopper 26 connects the limit switch 25 when the searchlight head 1 is located on the front axis (positive center), and the mode of the external switch SW when the controller 9 detects the signal. The searchlight head 1 is opened or closed in accordance with the signal given by the selection.

The controller 9 is installed on the driver's seat side or the mode of the external switch (SW) attached to the wireless remote controller according to the mode selection of the beam light (4), up and down rotation motor (7), left and right rotation motor (17), opening and closing motor (22) The limit switch 25 is connected on the condition that it outputs to each and drives the open / close motor 22, respectively.

In the present invention mainly deals with the structure of the searchlight, the algorithm that can be presented in various ways is not mentioned separately. However, at least the basic mode of the external switch SW and the basic role of the controller 9 for the operation of a searchlight are related to the operation of the present invention.

The external switch SW has at least a lit mode for turning off the beam light 4, an unlit mode, an open mode and a closed mode for opening or closing the search head 1, and for rotating the search head 1 side to side. It has a left turn mode and a right turn mode, an up mode and a down mode for rotating the light cover 6 in the search head 1 up and down.

In the lit mode and the unlit mode, the controller 9 applies or cuts off the power to the beam light 4. In the open mode, the controller 9 rotates the on-off motor 22 forward, but in the closed mode, the left and right rotation motors 17 are driven first before the closed motor 22 is reversed, so that the stopper 26 is the limit switch 25. Only after is connected, the closed motor 22 is rotated in reverse. This is a function given because the searchlight head 1 is not stored unless it comes to the correct position. In the left rotation mode or the right rotation mode, the left and right rotation motors 17 are rotated forward or reverse, and in the up or down mode, the vertical rotation motor 7 is rotated forward or reverse. However, the controller 9 should remember the operation of the open mode when selecting the four modes and the above-described on and off modes. That is to say that the output for the left and right rotation, up and down rotation and turning on only when the search head (1) is open in accordance with the selection of the open mode initially. In a practical design, it would be desirable to integrate the lit and open modes, and the unlit and closed modes.

The up-and-down rotational motor 7, the left-right rotational motor 17, and the open / close motor 22 are all reduction gears.

Hereinafter will be described the operation sequence according to the above configuration. First, when the searchlight does not operate, the searchlight head 1 is accommodated in the lower case 14 as shown in FIG. 2. In FIG. 5, the searchlight operating structure of the present invention is a rectangular warning lamp having a plurality of reflecting lights 32 and flash lamps 33 provided with transparent casings 31a and 31b, respectively, having a speaker case 34 at the center thereof. This is an example of application. That is, the components of the present invention including the searchlight head 1 are installed in the center of the speaker case 34 in which the speakers are built in both sides. Thus, when the searchlight head 1 is closed (when stored), the case 2 of the searchlight head 1 is integrated with the outer surface of the speaker case 34, and when the searchlight head 1 is opened (protruded). Is shown in FIG. 5.

Fig. 2 shows the closing time as in the former, and Fig. 1, Fig. 3 and Fig. 4 shows the opening in the latter. In the closed state as shown in FIG. 2, the free end of the bracket 13 is lowered, the female screw gear 19 is also lowered and positioned in front of the slot 18, and the limit switch 25 is connected by a stopper 26. It is in a state.

In this state, when the external switch SW is selected as the open mode in order to use the searchlight, the controller 9 outputs the open / close motor 22 to rotate the open / close motor 22 forward. Then, the male screw gear 21 is raised while the male screw gear 21 rotates forward by the worm 23. When the female screw gear 19 is raised, the pin 20 on the outer surface of the female screw gear 19 is guided to the rear of the slot 18, and the bracket 13 and the searchlight head 1 axially installed on the bracket 13 are hinged ( It rotates up around 15) and becomes as shown in FIG. The controller 9 recognizes a state that the opening (open state) of the searchlight head 1 has progressed until the closed mode signal is input.

In this state, when the external switch SW is selected in the upward mode to direct the light axis of the beam light 4 upward, the up and down rotation motor 7 rotates forward. As a result, the two-link link 8 moves clockwise. The light cover 6 rotates upwardly about the hinge pin 5. 3 shows such a state.

When the external switch SW is selected in the downward mode so that the optical axis of the beam light 4 faces downward, the up-and-down rotation motor 7 rotates in reverse, so that the two-link link 8 moves counterclockwise. While the light cover 6 is rotated downward about the hinge pin (5). 4 shows such a state.

FIG. 4 shows a state in which the searchlight head 1 is rotated 180 ° left or right in the initial open state as shown in FIG. 1. This case is possible when the external switch SW is selected as the left turn mode or the right turn mode. When the mode selection for the left and right rotation is made, the controller 9 outputs to the left and right rotation motor 17 to rotate forward or reverse. Accordingly, the driving force of the left and right rotation motor 17 is transmitted to the rotating shaft 10 through the gear 16, so that the searchlight head 1 rotates in the corresponding direction on the bracket 13. When the searchlight head 1 is turned left or right and moves out of the forward position, the stopper 26 is spaced apart from the limit switch 25 so that the limit switch 25 circuit is closed. This state is recognized by the controller 9.

When the searchlight is not used in the above state, that is, when the beam light 4 is turned off and the external switch SW is selected as the closed mode to be stored in the lower case 14 (to be closed), the controller 9 is left and right first. Output to the rotary motor 17 to rotate the searchlight head (1) in one direction. Therefore, when the stopper 26 connects the limit switch 25, the left-right rotation motor 17 is stopped. In this state, the searchlight head 1 is in the correct position toward the front. The next moment, the controller 9 outputs to the open / close motor 22 to rotate the open / close motor 22 in reverse. Then, the female screw gear 19 is screwed down by the reverse rotation of the male screw gear 21 according to the power transmission of the worm 23 comes down. When the female screw gear 19 descends, the pin 20 of the female screw gear 19 is guided forward of the slot 18 and the bracket 13 rotates downward about the hinge 15. Therefore, the searchlight head 1 rotating together with the bracket 13 is stored in the lower case 14 and closed to return to the state as shown in FIG.

The present invention configured as described above can freely rotate the beam light up, down, left and right even under a compact structure. When applied to a rectangular beacon, the exterior of the rectangular beacon is beautiful because the head of the searchlight can be projected to the outside only when it is stored and kept similar to the speaker cover. In addition, when the searchlight is not used, the searchlight head including the lens and the beam light is stored inside, so that foreign substances such as dust are not frequently caught, thereby avoiding frequent cleaning and maintaining optimum illumination.
